不同类型情绪对认知抑制的影响The Effects of Emotion on Cognitive Inhibition

本研究采用3(情绪类型：正性、负性、中性)× 3(任务类型：一致、不一致、无关)的被试内实验设计，考察了情绪对认知抑制的影响。以38名大学生为被试，从中国情绪图片库中选取正性、负性和中性图片各60张，并在stroop任务前呈现情绪图片，要求被试判断stroop任务中的汉字颜色。结果发现，任务类型主效应显著；情绪类型与任务类型的交互作用显著，与中性情绪条件相比，在正性情绪和负性情绪条件下，被试完成stroop任务更难，stroop效应更大，表明情绪对认知抑制的阻碍作用。To investigate the effects of emotion on cognition inhibition, a 3 (emotion type: positive, negative and neutral) by 3 (task type: congruent, incongruent and neutral) within subject design was conducted. Thirty eight university students participated in the experiment, emotional pictures (60 pictures for positive, negative and neutral scenes each) selected from the Chinese Affective Picture System (CAPS) were used as experi- ment materials to induce participants’ emotion and showed before the stroop task, in which the participants were asked to name the color of the word printed and ignore the word meaning. The results showed that the main effect of task type and the interaction of emotion type and task type were significant, further analyses revealed larger stroop effect for emotion condition than neutral condition. From the current results, we can conclude that emotion (positive and negative) can disrupt cognitive inhibition.
